Skip queues at The Sagrada Familia
The Sagrada Familia is one of the most famous and visited buildings in the world. The queue stretches out as a long line under the sun, which you're guaranteed to come across unless you visit before it opens in the morning or just before closing. Don't be one of those people who respond to the question "Have you seen the Sagrada Familia?" with "Only from the outside, the queue to get in was too big!". So what's the easiest way to beat the queues to get into the Sagrada Familia?
One easy way, which many visitors fail to do, is visit the official website and in the ticket section and book from there. You see, at the Sagrada Familia there are essentially two queues - the first to buy a ticket and the second to get in - so by buying in advance online you're effectively skipping a queue completely. Print your ticket and present it at the entrance, or show the booking confirmation email from your smartphone as it works with the QR code. In this special queue there are usually only about 4-5 people, so you could be inside within minutes.
Alternatively you could simple opt to visit some of the many other churches of Barcelona.
Don't wait in line at Casa Batlló and La Pedrera
The queues of Casa Batlló and La Pedrera aren't exactly short either, but in both cases you can still buy a ticket online to get faster entry. To visit Casa Batlló, all you need to do is visit the official website and go to the ticket section. There are various options, but in order to skip queues here you'll have to pay €5 for the privilege of a Fast Pass, so just mark that option. There is a special entrance for people who have Fast pass, so you'll get in quicker.
If you are visiting La Pedrera, it's more or less the same in that you need to go to their website and buy the ticket that suits you. You'll need to pick the date and time and print your ticket off. Alternatively there is a "Premium ticket", which allows you to turn up to La Pedrera without any queues at the "VIP entrance" on the day you want, at any time within 6 months of getting the ticket.

Just be certain to make sure the agency you're buying from is accredited and secure. You'll be able to print and show the ticket at the entrance.
